There is one simulator available using pySNMP called SNMP simulator.
It sets a default context name value.
Is there anyway to set custom context name value for snmpv3 ?
Here is an extract from snmpsimd.py where i tried to give context name value.
config.addContext(snmpEngine, '')
Giving value as custom parameter is not setting value there.
If you are building an Agent, you should register your contextName at SnmpContext class instance. See examples here and here.
If your app is a Manager based on pysnmp's high-level API, you should pass contextName to getCmd/setCmd(). See example an here (search for contextName).
Please clarify your task if my suggestions do not help.

I follow the tutorial to set up a TraceLoggingProvider in my application.
During the application runs, I try to use xperf -providers to see if my user event provider is there:
I cannot see the name I defined in TRACELOGGING_DEFINE_PROVIDER but only the defined GUID is shown. Is it intended?
Instead following another tutorial with WPRP file, I just use xperf -start to capture events. And the same: I can only use GUID as parameter, not the defined name! is it also intended?
Anyway, at the end I can view the result properly in WPA and the defined name of my user event provider is visible.
are all my observaton intended?
The name you use in the C++ code is unrelated to the display name on your pc.
You'd have a displayed name (instead of GUID) if this was a manifested installed provider, but TraceLogging isn't manifested (at least, not in the classical sense - an impromptu manifest is embedded into the image, and sent in the messages).
I am using the PublishKafka_2_0 processor and need to disable SSL endpoint identification algorithm while connecting to Kafka. From the docs I can do this by setting the following producer property to an empty string:
ssl.endpoint.identification.algorithm=
The documentation of PublishKafka_2_0 mentions that this can be set using dynamic properties. Can someone show how to set this property? A screenshot or link to an example would be great.
I am using NiFi 1.9.1 and Apache Kafka 2.1.1
Thank you
While I strongly discourage disabling endpoint verification, to accomplish this, click the + icon on the top right of the processor properties tab, enter the value ssl.endpoint.identification.algorithm for the dynamic property name, and check the "Empty string" box for the value of the property.
I only took a quick look, but I do not see that property defined in the ProducerConfig class in the org.apache.kafka:kafka-clients-2.0.0.jar dependency. If the predefined string is not present, you may get a validation error in NiFi of "Must be a known configuration parameter for this kafka client".
I am currently working on a windows service (which starts so that is a good thing).
The big question is how can I get parameters in the start parameter field (without doing it manual ofcourse).
So what I would like to see is the following. Upon installation of the service I would like it if the following happens.
The services gets installed and the start parameters are set.
How would one do such a thing (already been browsing StackOverflow but it doesn't comply with what I want)
The reason I ask the question is the following: The service is part of a communication layer between GUI and a receiving backend. If the backend location differs (e.g. another IP address) the service needs to have the new address accordingly.
If you would like to have some more info please ask (don't down the post if something is not in order 'just ask :)')
Thanks in advance
After the update of your question, I understand what you are trying to accomplish. As far as I currently know, it is not possible to set these start parameters without using the registry. You'll have to do it manually from the services console or by using an installer. When you look at the MSDN page covering ServiceBase.OnStart (MSDN ServiceBase.OnStart method) it clearly states:
Process initialization arguments for the service in the OnStart method, not in the Main method. The arguments in the args parameter array can be set manually in the properties window for the service in the Services console. The arguments entered in the console are not saved; they are passed to the service on a one-time basis when the service is started from the control panel. Arguments that must be present when the service is automatically started can be placed in the ImagePath string value for the service's registry key (HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\). You can obtain the arguments from the registry using the GetCommandLineArgs method, for example: string[] imagePathArgs = Environment.GetCommandLineArgs();
Thing is that you will still have to keep track of these registry settings when removing the service.
Therefore the link provided here ("Am I running as a service") might help out as well.
use sc.exe:
c:\>sc config <myservice> binPath= "\path\to\myservice.exe -param -param"
In your OnStart() or your service thread use something like:
string myArg = ConfigurationManager.AppSettings["MyArg"]
where in your App.Config you've added
<appSettings>
<!-- My keys -->
<add key="MyArg" value="xxx"/>
</appSettings>
Start a Windows Service passing arguments by using the System.ServiceProcess ServiceController Start(String[]) method like this:
ServiceController sc = new ServiceController("BDESVC");
sc.Start(new string[] { "argValue" });
How do I run/call/kickoff an external program (custom code) whenever certain attributes or objects are added or modified in OpenDJ’s database?
Here is my real world need. (Feel free to change my thought direction entirely).
Whenever a new email address gets created or changed in the OpenDJ database I want to initiate some java code that does some email verification/validation (send the “click here” link with a token to prove the user owns the email they just signed up with).
I know, I could use OpenIDM/AM to accomplish this but to take this a step further I need to validate other information and other credentials (custom) which users supply that are not supported by OpenIDM/AM suites.
Initiating/calling custom code upon ADD or MODIFY of specific objects and attributes is what I want and would like to know how to accomplish this. Preferably without having to scrape logs.
Please Help.

OpenDJ has a plugin interface where you can plug Java calls on Add or Modify. A sample of this kind of plugin is the attribute uniqueness which verifies that some attributes have a unique value in the directory.
The plugin interface javadoc can be found here : http://docs.forgerock.org/en/opendj/2.6.0/javadoc/org/opends/server/api/plugin/DirectoryServerPlugin.html
I have been using bindings without having ever heard of exposeBinding.
Is it only intended to plug-ins ?
What does exposeBinding do ?
Expose bindings are nothing special, it is just normal binding what you see in the Xcode. But why its named is expose binding becuase when you do any binding in the interface builder. It causes second binding automatically in the interface builder which is called expose binding.
For your understanding i have attached the screen shot in which inside binding inspector i have just bind file owner to the hidden in Availablity section and then you can see below automatically it created hidden2 inside Availablity section below. This new binding hidden2 is called exposed binding. And also the used of these binding values are then used together in returning the final value of the binding. Please follow the attached screen shot:-
From the doc.
exposeBinding:
Exposes the specified binding, advertising its availability.
